273 Engine set up I'm thinking of going with, let me know what you think

When you mean net rating, are you meaning crank hp or bhp

I was talking crank hp, but more of a real world installed in the vehicle configuration. Mean with air filter, exhaust, accessories, etc.

Obviously it's just a guess, but I do think you can have nice driving street engine, and make enough power to run in the 14's if you ever wanted to make a few passes.

P.S. I should note that I was considering headers were in the mix also.
